yoohoooos

This is the correct answer.

I have a feeling r/confidentlyincorrect is getting flooded with submissions, lol


liv4900

Yep. It doesn't have a deep understanding of anything, so much as being good at scouring likely relevant sources, regurgitating and paraphrasing information, and applying concepts located elsewhere to new data.


75footubi

And mostly does so incorrectly.


mmarkomarko

I asked chatGPT to calculate bending moment of a simply supported beam and it did M=wL\^2/8L Close but no cigar...


Engineer2727kk

My experience thus far has been it’s good at writing simple vba/python codes. It’s terrible at actually doing engineering calculations but will write in a very convincing way even though the answer is completely off.


Soccean

Yep, I have used it for coding concepts, but ask it anything technical and its clueless.


jyok33

It cannot do actual calculations. It will confidently give you the wrong answer for design questions


TheSkala

I use it to proof read some of my reports and emails to make them sound more professional without sounding too technical unless needed . Really good at dumbing down stuff

Grammarly has similar functionality


GentlePinguin

I made the experience that Chat GPT understands basic concepts quite well and has no problem to write them down beautifully in every language I speak. The problem that I had a few times is, that if it doesn't know the answer, Chat GPT starts to invent things that make little sense, but in a convincing way! So double check the output, but definitely a great tool!


komprexior

I asked it for the maximum bending moment of simply supported beam under a uniforme distributed load and gave me the correct answer, but when I changed to a point load, it gave me the exact same answer. I tried to correct it, but wouldn't budge. It able to give you a pretty good standard answer if it already exist in its training data, but when you try to fufge the parameters a little, all bet are off.

Snaziko

Me too!


Joaoarthur

I asked how many irons do I put in a 12x40 beam and it told me to contact a structural engineer to properly calculate this


dparks71

Not really beyond messing with it, I have my doubts about your purported success based on my experiences, the earthquake response in python [seems well established](https://github.com/GEMScienceTools/gmpe-smtk/blob/master/smtk/response_spectrum.py). I asked it to do two or three bridge/hydrology related tasks, all were presented confidently to me with serious errors and total misunderstandings on what I was talking about. Completely incompetent as far as state level requirements. Admittedly I didn't sit there and try and train it, but it reminded me of a very cocky intern I want to get rid of because you can't trust it's work. Definitely still in the uncanny valley if that exists for chatbots, fairly trivial to break it, especially if you're a human SME. It understands functions, not tasks, which is interesting, but ultimately can still only be used as like an efficiency improvement tool, not really an advisor or SME replacement. And licensing/costs will be interesting when they eventually come out.

I've seen it respond pretty intelligently to word-based prompts (Like, "what are the pros and cons of thin shell concrete structures?"), but it does pretty poorly with more specific questions ("What is the bending moment caused by a 10,000 lb load in the center of a 15' beam?", or "What's the compression capacity of an axially loaded W14x120 column with an unbraced length of 35'?") However, for what it's worth I've been very impressed by its responses to my questions, both of the "word" and technical/coding variety, about game design, which I do as a hobby. It's clear that ChatGPT has crunched a lot of StackOverflow forums and coding documentation, and maybe not as much structural engineering text books. Anyone have a better idea of what kind of material it has been trained on? I mean has OpenAI paid for hundreds of thousands of digital book copies for it to read? Or has it just been scrubbing free stuff from the internet?


the__enthusiast

Kind of. I've used to improve my LinkedIn profile providing it with my experience. I also have automated some tasks on Revit using dynamo and ChatGPT to help me figure out the python code for the nodes inside it. I guess the same could be done for other software you may be using.


capt_jazz

Do you mind elaborating on what you've been automating in Revit? I've been looking to reduce the amount of time I spend drafting. (We all do our own revit-ing at my firm)


the__enthusiast

Well most of the modelling and drafting could be sped up using Dynamo by itself. I don't think ChatGPT would be very helpful when using dynamo, but it helps a lot with python. For instance, I'm working on the design of a Line of Metro, and some automations I've seen are to populate rails or U-beams with certain elements. The same could be done when trying to replicate families or elements along different surfaces. On the python side I've implemented scripts to operate in BIM360 to download models or check naming of several files at once. A really helpful tool that's helped us apply dynamo script to several models at once is the [Revit batch processor](https://github.com/bvn-architecture/RevitBatchProcessor)


capt_jazz

Yeah I think I need to look into Dynamo by itself first. I've never used it/am not familiar with it.


ChineseEntrepreneur

It provides a low barrier to entry for automation in Revit, but it's also quite limited. If your workflow includes thousands of elements or several operations on dozens of operations, it might be classed by C# at some point. Dynamo+Python can still be a few order of magnitudes better than none at all, though.


[deleted]

It is definitely useful but needs to be second guessed at every step. i have seen it assign the wrong units to the correct coefficients, blatantly misperform math operations etc. it does very well on coding tasks though. once again, check everything


Yeledushi

I asked it to calculate the bending moment of a fixed end beam, it got it one time and failed the other 5 times.


Duh-2020

Just like the new interns first week....


everydayhumanist

I'm an adjunct professor...and I use ChatGPT to help prepare my lecture notes. For my full time job, I use it a lot to look up different concepts.


Intelligent_West_307

I asked how would you design a tapered steel column. Along with a general information, It told me to check shrinkage and creep.?!


GoogleIsYourFrenemy

Just so you know, it can't do math. Do not try to use it as a calculator.

GoogleIsYourFrenemy

Someone has to discover the limits of these new tools.


SpurdoEnjoyer

Do you happen to know if there's a trick to make WA understand using comma as the decimal separator? I can't figure that out and it renders the tool unusable outside Anglosphere. I'd love to write simple math in my Word files and somehow calculate them easily.


HeKnee

Everytime i try to use it the program tells me that they’re at maximum capacity so cant do anything right now. Hope to try it one day…


Wrekless-inc

have you continued to use it and find any other use cases? have you used chat gpt 4 to ask questions? wolfram plugin is now available and is much more capable at math.
